Platinum Solder


#1

Juergen,

The heat sink ‘tip’ was intriguing. A dental tech many many
years ago showed me how to solder a higher melting point solder
onto a piece of metal with a slightly lower melting point by
judicious use of a combination of copper heat sinks and a pair
of frozen house bricks set on fire brick. The torch flame
needed to be slightly ‘harder’ than a brush flame and at the
precise moment the solder began to melt you would exhale a lung
full of carbon dioxide directly on the work, otherwise the
solder wouldn’t flow and the metal would ball up. This was his
way of teaching me torch control and coordination in order to do
a technique where the tooth structure is built up on flat-pin
facings made of platinum gold (?) alloy that have been soldered
together with hi-heat solder. The remainder of the tooth
structure was built with successively decreasing ‘heats’ of
solder to form the part of the tooth that was not part of the
flat-pin/porcelain facing.

The reason I’m writing is to ask about those uses for a
’Sharpie’. Please tell us! Some time ago someone else alluded
to your ‘Sharpietricks’ too. If you have already done so please
repeat them. I have spent so much time in the hospital this
past year I may have missed them.

Regards,
